A TT ORNEYS.

Patented Oct. 10, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to new and useful improvements in wall boards and is designed primarily as an improvement upon the structure disclosed in Patent 1,473,981 issued to me on November 13, 1923.

In the patented structure there are used furring strips of fibrous material over which is laid an open mesh wire fabric.

An object of the present invention is to dispense With the use of the furring strips and to employ, instead, an open mesh Wire fabric so shaped and applied as to properly hold the stucco or other covering material to the Wall board.

A further object is to provide an improved l5 means for connecting the Wire fabric to the remainder of the Wall board structure.

With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of 20 construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the 25 invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing:

Figure 1 is an elevation of a portion of a wall 30 board construction in accordance with the present invention.

Figure 2 is a section through the wall board taken on the line 2 2, Figure 1.

Figure 3 is a section through a portion of the 35 Wall board taken on the one line 3-3, Figure 2.

The base of the wall board is made preferably of two thicknesses of paper indicated at I and 2 preferably of about 16 point while interposed between these layers is an intermediateV sheet of 40 paper 3 which is heavier, being preferably of about 30 point. These thicknesses are held to gether by interposed coatings of asphalt shown generally at 4.

To one surface of the base is applied a layer 45 of loose fibers indicated at 4 and over this layer of bers is placed an open mesh Wire fabric 5 having regularly spaced offset portions 6 which are parallel and are held to the base by staples 'l formed preferably of fiat strips of material 50 which are extended over some of the wires in the offset portions 6 and are clenched or otherwise fastened in the base. Thus these offset portions constitute supports for holding the remain- (Cl. l2-116) ing portions of the wire fabric spaced from the base of the wall board. Consequently, when stucco or the like is applied to the wall board, it will become properly keyed thereto even though furring strips are not employed because the anchored fibers and those portions of wire fabrics spaced from the base will act properly to engage and hold the applied surfacing material.

As the result of using a wall board such as herein described, the cost of production is mate- 10 rially reduced because it is not necessary to provide furring strips for holding the Wire fabric spaced from the base of the board. Furthermore this wall board can be produced by much simpler methods of manufacture than would otherwise be possible.

A wall board such as herein described serves to protect from moisture any wooden structure to Which it might be applied and consequently, the danger of the applied plaster or stucco cracking as a result of expansion and contraction of the Wooden structure due to absorption of moisture and subsequent drying, is practically eliminated.

If desired, and as shown in Figure 1, a desired number of strands of cord or other reenforcing material can be pressed between the layers of paper. These strands have been indicated generally at 8 in the drawing.

What is claimed is:

l. A composition wall board comprising a base of connected thiclmesses of paper, an open mesh wire fabric overlying one surface of the base, said fabric having spaced offset portions, and means anchored to the base for holding the offset portions thereto, said oifset portions constituting means for holding the remaining portions of the Wire fabric spaced fro-m the base, and fibers loosely positioned between the wire fabric and the base and held assembled with the base by the fabric.

2. A composition Wall board including a Waterproofed paper base, an open mesh Wire fabric overlying one surface of the base, said fabric having regularly spaced parallel offset portions, and means for fastening said offset portions to the base, said offset portions constituting means for holding the remaining portions of the fabric spaced from the base, and fibers positioned loosely between the base and fabric and held to the base solely by the fabric, said fibers being grouped in separate areas spaced apart by the offset portions of the fabric extending therebetween.
